Avalanche Forecast

Moderate

No new avalanches have been reported, but observations have been very limited in this region.

We expect that widespread, large, natural and human-triggered avalanches will be very likely throughout the storm.

Travel in avalanche terrain during periods of rapid loading from new snow and wind are strongly not recommended.

Over 150 mm has fallen as snow in many high elevation alpine areas, or as rain at treeline and below, since last Saturday.

Another 50 to 90 cm of snow is expected, with heavy rain again at lower elevations. The freezing level may fluctuate between 1000 m to 1500 m throughout the storm. The heaviest precipitation amounts will be between Powell River and the North Shore with the lesser amounts to the east toward Hope.

In the alpine, extreme winds are expected to form deeper storm slabs on lee northeast through northwest-facing slopes.

Expect a rain-saturated snowpack or lack of snow at lower elevations

• Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
• Storm slab size and sensitivity to triggering will likely increase through the day.
